4.5/5

The cheapest fillet knife on our list, the 7″ Kershaw fillet knife features a Japanese 420J2 high carbon stainless steel blade that boasts excellent edge retention and corrosion resistance.

Overall, Kershaw delivers a solid fillet knife, that offers the frugal shoppers a good option to fillet their fish with.

What To Look For In The Best Fillet Knives

Below, we’ll cover the main factors to consider before selecting a fillet knife.

Blade material

There are three different materials from which the fillet knife blade is made:

  • Stainless steel
  • Carbon steel
  • Ceramic

Stainless Steel

Stainless steel is a good choice for fillet knives because it’s rust resistant and non-corrosive. While the blade will hold a sharp edge, it can become dull quickly.

While stainless steel is good at resisting rust and corrosion, it’s still a good idea to care for the fillet blade properly. Be sure to dry the blade immediately after use, and keep it in a safe place to prevent damage.

Carbon Steel

Carbon steel is a popular blade material. It can be sharpened to a razor-like edge and hold it for a longer time than a traditional stainless steel blade.

The blade is made from carbon steel, a metal alloy consisting of carbon and iron, which is then hardened. This provides a good, strong blade that maintains a sharp edge.

Using a carbon steel blade may be better for certain filleting situations, but there are some downsides. The blade will rust if not cared for properly, and you’ll need to be careful about the way you store it away from moisture.

So if you’re going to be filleting mostly in the kitchen, a carbon steel blade will likely work great, but if you’re going to be using your fillet knife when out and around the water, you may want to avoid this material.

Ceramic

Ceramic is another material option for fillet knife blades. It provides both a sharp edge and is not susceptible to corrosion as either carbon steel or stainless steel are.

However, the main downside of ceramic in relation to filleting is that the blades are very hard and do not flex. This can make it difficult to fillet a fish effectively, and you’ll likely miss out on a lot of the meat.

The other consideration is the brittle nature of ceramics. If you were to drop your fish fillet knife you can easily crack the blade.

So, with all of this in mind, we generally recommend investing in a blade with the highest grade of stainless steel available. Stainless steels will have a longer lifespan, won’t tarnish and will not rust when wet.

Blade length

The blade length of your fillet knife will likely depend on how much fish or meat you typically work with, as well as where and how you like to fillet.

If you’re planning on catching a lot of smaller fish, you’ll probably want a smaller fishing knife with a shorter blade length. This will also be good if you like to fillet on the go – for example, if you like to spend your weekends fishing.

A smaller blade length will make it easier to work with and will allow you to get into the tighter spaces and fillets that are necessary when filleting smaller fish.

If you plan to fillet larger fish, a longer blade will be great.

Longer fillet blades will allow you to work with larger fish a lot easier. They will also be better suited for filleting in-home – for example, on your kitchen counter.

The blade of a fillet knife should be between 4 and 10 inches in length. The longer the blade is, the more challenge it will pose to control.

Four to six inch blades will be easier for you to control and produce cleaner cuts than shorter blades, but it can also do an excellent job when you combine with good technique.

Six, seven, and eight-inch blades are perfect for slicing trout and eater-sized walleyes.

Nine and ten-inch blades offer extra length for cutting larger fish such as supersized salmon and other saltwater fish.

Blade Flex

Blade flex refers to the degree to which the blade will bend when you apply pressure on it.

Blade flex is something you should look for in a fillet knife.

Flex is essential because it allows the blade to contour itself around bones and other hard surfaces, making your job easier. Look for models with blade flex of at least 25-28 degrees to ensure maximum flexibility.

If they’re anything less than this, keep looking because there are knives with better flex.

So, to obtain a flexible blade for your fillet knife, you need to check that it is made up of quality stainless steel. A great mixture of superior grade carbon and chromium will help with flexibility as well as durability. ​

A flexible blade is crucial because it allows you to get around the bones and contours of the inside of the fish. In addition, some models will have non-slip handles that add to your grip on the knife and facilitate getting them through tight spaces with ease.

Knife Handle

You should select a fillet knife handle that is comfortable in your hand. It should feel solid and stable in your grasp, yet not too cumbersome.

The knife’s grip should allow you to keep a firm hold on it even when wet and slippery with fish slime and blood.

The handle of a fillet knife is usually made from several materials such as wood, plastic, and rubber. The material plays a crucial role in making the knife comfortable for its use and can also impact your grip and comfort.

That makes it crucial to get a quality handle for enhanced performance when handling fish.

The handle’s material will determine how comfortable it is in your hand and whether the knife is durable or not.

Wood fillet knives have a classic feel to them and a good grip that offers control during use.

The disadvantage of wood fillet knives is that they need regular cleaning when using saltwater fish. They are prone to cracking and quickly soak up unpleasant odors; thus can be challenging to clean.

Plastic fillet knives have a good grip for control during normal use, but can become slippery when wet or slimy.

Rubber fillet knives usually come with a rubberized D-grip that enhances stability and control. Rubber handled fillet knives are typically the best option when you’re wanting to fillet outside the kitchen as they’ll provide the most grip and won’t become slippery when used.

A good handle for a fillet knife should be about 5 inches long, so it can accommodate most filleting jobs and allow you to keep a good amount of blade in contact with the cutting board. The size of the knife handle should be proportional to your hand. A larger handle provides a more comfortable and stable grip

Sheath

The sheath options available for fillet knives include plastic, nylon, or leather.

A plastic sheath is typically durable and dries quickly, which makes it an excellent choice as it will protect the blade from rusting and reduces cleaning time.

However, a leather sheath is the most preferred since it provides safety when on board because it covers the blade’s sharp edge and prevents injury to fingers or other body parts.

If you are using the knife in your home or at the campsite, then a nylon sheath will work fine.

Choose a sheath that has ample ventilation so that the blade stays dry and protected from corrosion. A knife sheath will protect you and the edge against being injured by the knife. The fillet knife’s sheath should be comfortable and secure with a belt loop.

Many sheaths come with swivel studs which enable quick and easy attachment to belts or straps.

A perfect knife sheath should be well-fitted to its intended knife and able to protect the blade from impact, keep it dry, and allow easy access. Ensure the sheath doesn’t add any obstruction or impediment to pulling a knife from it quickly.

Conclusion

Investing in a quality fillet knife will have lasting effects.

It’s better to buy a good and durable fillet knife that will function efficiently than purchasing a weak knife. There are several factors to consider when you’re looking for the best fillet knife.

To help you out, we’ve put together a quick list of the most important factors to consider when buying your fillet knife.
